How exponent calculator works
Exponentiation is a mathematical operation where a base number is raised to the power of an exponent. The exponent tells you how many times to multiply the base by itself. For example, 2 to the power of 3 (written 2^3) equals 2 times 2 times 2 = 8.
This calculator handles all types of exponents. Positive exponents multiply the base repeatedly. Negative exponents produce the reciprocal (2^-1 = 0.5). Fractional exponents compute roots (4^0.5 = 2, the square root of 4). Zero as an exponent always gives 1 (except 0^0, which is undefined).
Very large or very small results are displayed in scientific notation for readability. The calculator uses JavaScript Math.pow, which handles the full range of double-precision floating-point numbers.
